you can compare a cell membrane to a strainer because it controls what drains out or stays in
a gate
cell membrane
Many textbooks will compare a cell membrane to the fluid mosaic model, which means that the parts of the membrane (phospholipids, cholesterol, proteins etc.) are not stuck in one place; they move around and can pass by one another while still keeping the integrity of the membrane. That is mainly for the structure, but structure always lends to function.

I suppose you could compare the mantle to the cell wall or cell membrane.
Its called "the fluid mosaic model" of the cell membrane. This describes the clumping together of phospholipids to form rafts and their motion (along with single phospholipids) throughout the membrane.
Angiotensin is activated by a renal enzyme called

the cell membrane is as flexible barrier outside of the cell.
